How to split a Polyline Geometry at a certain point in ArcObjects?

[المشرف العام]

I have a polyline geometry and wish to split it into two different geometries, based on a given point on that line, in ArcObjects.

I have tried to find out how to do this, but to no avail. I found that there are three methods which are sort of related to what I want.

1. IFeatureEdit.Split Method This seems to do exactly what I want, but it Works on a Feature, and not on a Geometry. I Do not want to edit existing features, but copy the geometry from an existing feature, split it in two parts, and then process those parts.
2. IPolycurve.SplitAtPoint Method I though that this method would be useful, but it just adds a new vertex at the point, and does not split the polyline
3. ITopologicalOperator.Cut Method This would also work, but when I use it, giving a perpendicular line as the input paramter, I am getting an error which says 'An Internal error has occured in the geometry system.'

Is there some way of achieving what I want to do?
